Application filed November 19, 1908. Serial No. 463,390.

Tack pulling machines have heretofore been devised by which theprojecting lasting tacks may be removed from a lasted shoe preparatoryto the sewing operation, and these machines may also be used to removethe projecting anchor and stay tacks after the sewing operation of theshoeis completed. Machines have also been devised for withdrawing theinsole tacks which are driven in flush with the surface of the soleprior to the lasting operation, and serve to hold the sole in place uponthe last until after the sewing of the upper or upper and welt iscompleted. Prior to the present invention, no machine has been devisedwhich is adapted to remove both the projecting lasting, anchor andstaytacks and also to remove the flush insole tacks,'and in those caseswhere machines have been employed for removing the projecting tacks 1thas been necessary to either employ additional 7 machines for removingthe insole tacks, or to femove these tacks by means of a hand too It isthe object of the resent invention to provide a machine by w ich a partor all of the lasting tacks may be removed from the lasted shoepreparatory to the sewing operation, and by which the projecting lastingand anchor. tacks and also the flush insole tacks may be removed, afterthe sewin operation.

ith this object in view, one feature of the invention contemplates theprovision in a machine for pulling tacks from a lasted shoe of tackpulling devices and actuating means constructed and arranged to enablethe operator to either pull the tacks whlch project from the lastedshoe, or to pull the tacks which are driven in flush with the sole.

I Broadly considered, the invention contemplates the provision of anysuitable-tack pulling means which is so constructed and arranged thatthe operator may utilize the machine to pull the projecting tackswithout injury to the upper, ormay utilize the machine to withdraw thetacks which are driven in flush with the surface of the sole. The sameor dilferent tack pulling tool or tools may be employed for engaging andwithdrawing the projecting and flush tacks. In the simplest andpreferred form of the invention, however, thetack pulling device ordevices is so constructed that-the projecting and flush tacks arepresented in position to be operated upon by diiferent, parts of thesame tool or-tools.

A further feature ofzthe invention contemplates the provision in amachine provided with tack pulling means constructed and actuated toengage and pull either projecting or flush tacks, of work positioningdevices which are constructed and arranged to permit the operator topresent the lasted shoe in proper position for pulling the projecting.tacksor to present the shoe in proper position for the pulling of tackswhich are driven in flush with the sole. Broadly considered, thisfeature of the invention contemplates the provision of any suitable formof positioning devices which will enable the operator at will toproperly position the shoe for pulling either projecting or flush tacks.In the preferred form of the invention, however, the positioning devicescomprise means for engaging the upper and positioning a projecting tackin proper relation to the tack pulling devices, and a tack gage forenabling the operator to properly position the sole tacks with relationto the tack pulling devices, the positioning means and gage being soconstructed and arran ed that either may be brought into working arelation with the tack pulling devices at the will of the operator.

A further object of the invention is to provide an improved constructionof track pulling mechanism by which insole tacks can be readily andquickly pulled from a shoe in a more eflicientmanner and with lessdanger of injury to the sole, or of breaking the tack and leaving a partthereof in the sole or last, than with the devices heretofore employedfor this purpose.

relative shift-ing of the locating means and jaws to'brin'g the tackinto the path of the jaws as they are actuated to dig into the sole onopposite sides of the tack.

In the machine hereinafter described these features of the invent-ionare embodied in a machine' adapted to pull projecting tacks as" well asto pull-tacks which are driven in flush with the. sole, but it will beunderstood that these features are not limited in their application tosuch a machine, but may be embodied in machines which are '25 notintended for pulling or not adapted to pull the projecting lastln g,stay or anchor tacks.

In addition to the features of invention above referred to, theinvention also consists in certain devices, combinations andarrangements of parts hereinafter described and claimed, the advantagesof which will be apparent to those skilled in the artfrom the ollowingdescription.

The various features of the invention will be understood from aninspection of the accompanying drawings, in which-- Figure 1 is a frontelevation of the machine embodying the features of the present inventionin their preferred form; Fig. 2 is a side elevation looking from rightto left in Fig. 1; Fig. 3 is a front elevation with thetack pullingdevices and one of the work positioning devices removed; Fig. 4.

is a; vertical sectional elevation; Fig. 5. is a sectional view on line5-'5, Fig. 2-; and Fig.

6'is a detail view showing one of the tack v pulling jaws in front andside-elevation.

In the construction of machine shown, the

tack pulling devices comprise two 'aws 1 which are secured to the lowerends 0 levers 2 and are given a reciprocatory movement toward and fromthe work and also a vibratory motion toward and from each other. The jawcarrying levers are pivotally'supported at 3 upon a slide 4 mountedtoreciprocate in suitable guideways formed in the frame of the machine.The slide is connected at its upper end to a rod 5, the upper .60 end ofwhichis provided with a strap encirling an eccentric 6 on the shaft 7.During the operation of the machine the shaft-7 is continuously rotatedand the slide 4 and jaws carried thereby are reciprocated by theeccentric 6 to move the jaws toward and tack into position where it willfrom the work. During the reciprocation of the jaws, the jaw carryinglevers 2 are vibrated on their pivots 3 by means of cams 8 arranged'toengage rolls carried on the upper ends of the levers, the cams beingproperly timed with the eccentric 6 to move the jaws toward each. otheras they come into position to engage the tack to be pulled, and to openthe jaws after they have been moved upward and have pulled the tack. Thejaws are adjustably secured to the lower ends of the jaw carrying leversby means of clamping screws 9, and may be adjusted upon the levers byadjusting screwslO.

' In order that the jaws may be adapted to act-efliciently upon eitherthe projecting tacks, such as lasting, stay or anchor tacks, and alsoupon the sole tacks which have been driven in flush with the sole, theworking ends of the jaws are diiferently shaped at difierent points ontheir opposing edges.

-A part of the-working end of each jaw is chisel shaped, as indicated at11 in Fig. 6, so that this partof the working end will bite into andgrip the shank of a tack which may be located between the jaws as theyare brought toward each other. The rear part of the working ends of' thejaw are gouge shaped, and project slightly beyond the chisel,asjindicated at 12 in Fig. 6, so that the rear 'portion of the workingends of the jaws will act to dig into the sole when it is resented inposition to cut the path of I movement of the jaws, and will pass underthe head of a tack embedded in the sole and located between the jaws.

In order to enable the working edges 11 of the jaws to operate upon andpull a projecting tack without danger of injury to the upper, and alsoto enable the operator to conveniently and rapidly position the tacks sothat they will be engaged by the jaws, the machine is rovided withpositioning plates 13 arranged to engage the shoe on opposite sides ofaprojecting tack and to guide the roject between the edges 11 of thetack pu ling jaws. These plates also act as work supports for the workduring the tack pulling movement of the jaws. The work positioning lates13 are secured to the lower ends of evers 14 and project somewhat beyondthe lower ends of the levers, so that the tack ulling jaws may operateto engage the tacr close to the surface of the shoe which is pressedagainst the under surface of the plates.

In order that the work' positioning lates 13 may be moved out of workingreliition with the tack pulling jaws when it-is desired to pull insoletacks, the carrying levers are pivotally supported at 15 upon rock arms16, and'are connected to their upper ends by links 17 which are pivotedto the frame of the machine at 18. By rocking the arms 16, the platecarrying levers may be swung upward and outward to carry the plates 13out of working relation with the tack pulling jaws. I

The mechanism for operating the rock arm 16 to move the work supportsinto and out of working relation with the tack pulling jaws comprises aslide 19 having its upper end connected with the rock arms by means oflinks 20, and provided with recesses engaged by the bifurcated front endof a lever 21. The lever 21 is pivoted at 2:2

to the frame of the machine, and is normally held in position to retainthe work supporting plates 13 out of working relation with the tackpulling jaws by a spring 23. The lever is operated to move theplatesinto working relation with the tack pullingjaws through a rod 24connected with a treadle (not shown).

The means for enabling the operator to properly position a soletack withrelation to the tack pulling jaws when it is desired to operate upon.tacks driven in flush with the surface of the sole, consists of a tackpo- 25 sitioning gage 25 formed on the front end of a lever 26 which ispivotedat 27 and is provided at its rear end with an adjusting screw 28arranged to engage an arm 29 on the lever 21. A screw 28 is held inengage- 3c ment with the arm 29 by a spring 30. When the workpositioning plates 13 are in working relation with the tack pullingjaws, the tack positioning gage 25 is held in the position indicated inFig. 4 where it will not interfere with the proper operation of the workpositioning plates, or the operation of the tack pulling jaws upon theprojecting tacks presented thereto. The upper position of the gage 25'is determined by an adjust- 40 ing screw 31. When the lever 21 isoperated to move the work positioning plates 13 out of working relationwith the tack pulling jaws, the upward movement of the lever 21 allowsthe spring 30 to swing the lever 26 4 about its pivot, and thus move thegage 25 downward into position below the path of movement of the workingends of the tack pulling jaws. The lower position of the gage isdetermined by an adjusting screw 32. When in working relation with thetack pulling jaws, the lower end of the tack gage 25 is directly back ofand below the path of movement of the working edges 12 of the jaws, andthe operator may quickly and rapidly position a sole tack in properrelation to the jaws by bringing it into position directly in front ofthe gage holdlng the surface of the sole against the lowerend of thegage. Having thus ositioned the tack W without bringing the sur ace ofthe sole into the. path of movement of the tack pulling devices, theoperator may, then press the sole upward, the spring 30 yielding toallow the gage to move upward until the stop 31 ar- 'rests the upwardmovement of the gage.

This upward movement of the sole and gage brings the surface of the soleinto the path of movement of the working edges 12 of.

the jaws, so that as the jaws are advanced toward the workand are movedtoward each other, they dig into the surface of the sole on oppositesides of the tack and pass under ,the head of the tack. During theupward ortack pulling movement of the j aws, the gage acts as a worksupport for resisting the pull of the tack pulling jaws. By manipulatingthe treadle connected with the rod 24, the operator may'at will bringthe work supporting plates 13 into position to cooperate with the tackpulling jaws, and may rapidly and conveniently present any projectingtacks, such as last, anchor or stay tacks, to the tack pulling devices,without danger of injury to the upper, or may bring the tack the sametack pullingjaws shouldbeutilized for pulling both the insole andlasting tacks, nor is it essential, in case the same jaws are utilizedfor pulling all the tacks, that different parts of the working ends ofthe jaws should be differently formed, or that the insole and projectingtacks should be presented to different parts of the working edges of thejaws.

A tack pulling machine ,having, in combination,-opposed tackengaging jaws provided with working ends shaped to dig into the sole ofa shoe and pass beneath the head of a tack, and continuously operatingmechanism for actuating the jaws to dig into the sole on opposite sidesof the tack and pull the tack from the shoe, substantially as described.
